Musnad Ahmad ibn Hanbal is the collection of Hadith collected by the famous [Sunni] scholar [Ibn Hanbal] to whom the [Hanbali] [madhab] of Sunnis is attributed.

It is said by some that Ibn Hanbal made a comment in regards to his book which read as follows:

"There is not a hadith that I have included in this book except that it was used as evidence by some of the scholars."
